EP1167914A1 - Self-propelled projectile with armour-piercing core - Google Patents

Abstract

A self-propelled projectile comprises a penetrating core (1) that contains explosive material (4,3a). A hollow chamber (2) coaxial to the core contains a non-lethal substance. If the core is placed in a ballistic weapon, the same non-ballistic conditions as those of conventional weapons can be controlled so the drives, platforms and logistics can be used. The projectile can contain tear gas.

Description

The present invention relates to a self-propelled Projectile according to the preamble of claim 1 or 2.

With so-called peace-keeping measures it has happened proved that currently none of the multinational troops has suitable weapon systems. - For example a single entrenched sniper with only today heavy weapons can be fought if these safeguards are in place against tear gas and the like.

The tactical leaders of such missions are therefore the Call for weapon systems that target bunker targets break through without causing total object damage.

Attempts by Denel (Pty) Ltd, Firgrove, Republic of South Africa, have shown that it is possible to use an explosive also called explosive penetrator, through bunker targets like concrete, slightly metal-armored armor and sandbags to shoot, even if the impact speed in the target lies below the speed of sound. moreover the arrow in the target, i.e. behind the Armor to fragment by means of its central explosive charge and there a relatively large destructive effect to achieve.

The development of a special weapon system for heavy police operations (against bunker targets) can be financially will not be represented because the entire logistics conventional combat troops would have to be changed.

It is therefore an object of the present invention, an arrow projectile, in particular to use a detonating arrow in such a way that a locally limited effect is achieved in the target becomes.

The arrow floor is said to be the usual walls of buildings, bulletproof glass but also shelters made of reinforced concrete, light armored vehicles with aluminum alloy plates or hit barricades, especially from sandbags and persons behind it unable to fight or facilities put inoperative.

Furthermore, the subject of the invention is intended to be conventional Use weapon systems and / or concepts and before can be used above all with their launchers (platforms) his.

The invention is intended for both non-lethal and lethal acting inserts may be suitable.

This task is solved by the solution according to the characteristics of claims 1 or 2 fulfilled.

Surprisingly, a puncture core penetrates Bunker target and the like, without being damaged itself, so that active substances can be introduced into the target area are set to a preselected effect.

If such a punch core is used according to claim 2, this allows the use of existing weapon systems and especially from their existing platforms.

By simply replacing a warhead with one Bullet jacket of the same external ballistics, can be achieve a very targeted effect without, for example the training and logistics of the troop made significant changes experiences.

Advantageous refinements are in dependent claims characterized the subject of the invention.

A non-lethal agent is particularly useful for police operations suitable, for example, in raids or at Temporary hostage taking of one or more people temporarily Combat sets claim 3.

It is particularly simple, highly tear-causing agents to be transported behind a wall or behind bulletproof glass, if they are of the type according to claim 4.

The design of a floor according to claim 5 results a lethal weapon acting in a larger room.

A stepped tip according to claim has proven particularly useful 6, which was practically undamaged and also heavily reinforced Penetrates concrete walls.

A taper of the arrow shaft according to claim is advantageous 7, since this is the frictional resistance when penetrating reduced.

By suitable notches, claim 8, for example in In the axial direction, the punch core can be kept to a minimum Forces to be opened from the inside.

A mechanical connection between the punch core and the container for the non-lethal agent provides for its automatic distribution; Claim 9.

The simultaneous or is of great tactical importance insulated storage of smoke agents according to claim 10th

In the following figures, examples of the Subject of the invention shown.

In Figure 1, 1 denotes an arrow-like punch core. This has a cavity 2, which is the Tapered tip and merges seamlessly into a cap. In the front part of the cavity 2 is one Active charge 3, in the present case a desensitized one High-performance explosives stored without voids. Behind the Active charge 3 is a balancing spring 7 with a central ignition channel 8; after the spring 7 is a subpoena 4 arranged with a detonator 5 'of an autonomous Ignition device 5 forms a known ignition chain. A mounting flange is located at the rear of the punch core 1 6, the easy integration of the core 1 with a drive A not shown here allowed.

The tip 10 of the punch core 1 is towards the rear side discontinued. A relatively obtuse arrow angle α1 goes at a more acute angle α2 in a subsequent taper shaft 11 over; towards the rear is the cylindrical one Arrow shaft 12 tapers by a small angle β, which facilitates its intrusion into the target.

The shape of a punch core 1 shown in FIG. 1 shows a surprisingly good penetration, even in a speed range of 160 - 240 m / s. Obviously "clears" the hard tip 10 with an arrow angle α1, on which a characteristic energy of 50,000 Joule works, most materials away. - A clean one physical explanation for the phenomenal effect of Punch core 1 is not available.

The illustration according to FIG. 2 shows in simplified form a rocket to be fired from a tube 22 in the characteristic form of a bazooka. The launch speed v ₀ is a maximum of 300 m / s. The drive A is designed in a conventional manner, as is the rear tail unit 21. In contrast to the conventional rocket-propelled grenade, the penetration core 1, which contains a non-lethal active substance 3b, is placed behind the two-part ballistic hood 20 on the drive A.

Further details of this embodiment are shown in FIG. 3 remove.

In contrast to the representation of Fig. 1, this is a purely lethal penetration core 1. In the cavity 2 is an explosive charge 3a, in which additional a splinter-forming ring 3c (splinter matrix) is embedded is the one that detonates together with the fragmenting one Core 1 a variety of splinters of different sizes forms.

The mounting flange 6 is positively in the hood 20 here screwed. In the middle part of the hood 20 is a support ring 23 arranged, which merges into a centering ring 24 and the punch core 1 axially symmetrically centered. With an additional weight 25 the center of gravity becomes 9 - symbolized - in the same position shifted, like a conventional bazooka. The further design as the closure cap 27 (spiked dummy secure) and the rear adapter 26 easy attachment of the entire head to the drive A. The resulting outside ballistics is identical to that the usual bazooka, which is known to be a Contains shaped charge.

FIG. 4 shows the course of the speed of a device according to the invention as a function of the trajectory (firing distance) D from the shot to the point of impact on the target a _o and the detonation a _z .

Important for correct functioning and security the use of the subject matter of the invention is an ignition device, which from the secured state via an accelleration unlocking A-E and a retardation release R-E detonator 5 'in that shown in Figs. 1 and 3 Focus pivots.

Suitable ignition devices with an integrated ignition generator, Security elements and a high detonator Services are commercially available (EMS-Patvag AG, CH-7013 Domat / Ems; Type PEPZ-05). This detonator is said to have a shock resistance of 100,000 g. The way such works Detonator is described in detail in EP -A- 104 138 in connection with U.S. Patent 5,269,223. - It follows that the igniters on almost everyone with the Subject of the invention conceivable intended use are.

The punch core 1 is advantageously made of an alloy Quenched and tempered steel manufactured according to DIN 34CrNiMo6 also commercially available (Gebr. Böhler & Co. AG, CH-8304 Wallisellen; Type V155). The angle α1 is preferably Embodiment 70 °; the angle α2 is 30 ° and the β (suit) 1.4 o / oo. The hardness profile is for obvious reasons of the punch core 1 decreasing from the tip to the rear set.

It has been shown that modern explosives (PBXN-9's DYNO Defense Products, NO) the impact shock at the target survive and still no additional summons 4 to Ignition required.

The subject of the invention allows a completely new kind of Crime:

For example, a hostage-taker is entrenched in one Counter space of a bank, so by locating (bearing) the Mobile radio a through core 1 with capsaicin 3b in the direction Hostage takers are shot without any line of sight - A suddenly through a wall or barrier penetrating projectile paralyzes it Fright so that no opposition can take place within the next second, the core 1 detonates; a relative large amount of capsaicin is sprayed and sets the hostage-taker completely out of action for a long time, so that parallel the police walk into the building unscathed and can do their job.

In order not to endanger third parties, are used non-lethal agents such as tear gas, mist etc. only minor Amounts of explosives built into cavity 2. By suitable notches in the inner wall are already sufficient Centripetal forces around the active ingredient from a bursting Exit core or spray around it leave, especially if a mechanical connection (adhesive) between the drug container and the core consist.

Depending on the ignition device used, explosive charge more lethal or non-lethal agents can be an individual and safe fight against targets of different hazard potentials, take place over a wide range. The projectile and the punch core are accordingly modular and interchangeable optimized with regard to collateral damage and risk - As a rule, there is only a hole in the Size of the punch core in the target or wall to be penetrated, so that the consequential damage of a Are low.
